Mud-resistant polycarboxylate superplasticizer and preparation method thereof
The invention discloses a mud-resistant polycarboxylate superplasticizer and a preparation method thereof, and belongs to the field of concrete. The mud-resistant polycarboxylate superplasticizer is prepared from the following raw materials in percentage by mole: 15%-25% of unsaturated polyether macromonomer, 60%-80% of acrylic acid, 1%-10% of unsaturated phosphite amphoteric monomer, 0.5%-5% of initiator, 0.01%-0.5% of chain transfer agent and the balance of water. The mud-resistant polycarboxylate superplasticizer provided by the invention has good dispersity and dispersion retentivity, so that the mud-resistant polycarboxylate superplasticizer has excellent mud resistance.
本发明公开了一种抗泥型聚羧酸减水剂及其制备方法，属于混凝土领域。所述抗泥型聚羧酸减水剂的制备原料以摩尔百分比计，包括：不饱和聚醚大单体15%~25%，丙烯酸60%~80%，不饱和亚磷酸酯两性单体1%~10%，引发剂0.5%~5%，链转移剂0.01%~0.5%，余量为水。本发明提供的抗泥型聚羧酸减水剂具有良好的分散性及分散保持性，因而具备优异的抗泥性。
